(D) reduced the amount of phosphates that municipalities are allowed to dump
(E) reduces the amount of phosphates allowed for dumping by municipalities _________________

An action in past stops an action happened before it------>the pair of tenses : simple past and past perfect. Thus, we can eliminate C,D,E.
B seems ok, but it can not deliver the original meaning of the sentence as "allowed" is eliminated.
